Concrete armored joint form that provides one step installation and thermal transfer prevention as well as seating for joint filler

ABSTRACT

The objective of this invention is to provide ease of application for steel armored joints used in industrial concrete floor construction. It provides one step simple installation. Eliminates thermal transfer in low temperature environment to a higher temperature environment through the concrete slab. Provides simple elevation adjustment. Provides a substrate for joint filler compression. Eliminates the need for wood forms and field welding that produces waste. Elevation adjustment and the ease thereof are achieved by vertical slots cut in the plastic upright. The neoprene bolts are to be tightened when the steel is at the desired elevation. Two part armored joints separate as the concrete contracts during the curing process. Then the joint filler product is applied.

BACKGROUND OF INVENTION

Due to the required labor and material required to form and place anarmored joint with wooden forms in a concrete floor this inventioneliminates these steps by providing a one step set and alignment of thearmor joint. The form is left in place and requires no additional laborto remove conventional wooden forming materials. This invention alsoprevents thermal transfer for temperature differential between floorslabs, by example if the conditions of installation is required for aspecific room operating at a temperature of (−20 degrees) adjoining aroom separated by a wall but has a door way in said wall for conveyanceof product and operating at +35 degrees this invention provides a totalthermal break between the two slabs.

Therefore eliminating the thermal transfer and migration of the coldertemperature to the warmer.

This also provides a “seat” for the joint filler thereby solving theindustry issue of joint fill failure in the armor joint. This featureminimizes the continuing floor maintenance expenses as well asaccelerated fork lift maintenance and replacement.

BRIEF SUMMARY OF INVENTION

This invention eliminates wooden forming labor and material that isrequired for the installation of conventional steel armor joints. Thisinvention is a one step, set in place and leave in place product. Thearmor joint is fully adjustable to compensate for undulations in thesubstrate or if used on an insulated freezer floor. The product providea complete thermal break at the door locations between temperaturedifferentials in defined rooms, such as a freezer floor to a dock area.The base and upright provide a “seat” for the joint filler that will beapplied after the floors have cured and the armor joint separates, thusproviding a permanent base for the joint filler, therefore reducing theneed to reapply the joint filler.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawing FIG. 1 this designates the plastic base piece 1to which will provide a support base for stabilization and thedeterrence of thermal transfer from slab to slab to which the piece 2 asdepicted in FIG. 2 shall be attached. This is accomplished by use ofpiece 3, a self tapping, self drilling screw, as depicted in FIG. 3.Pieces 7 and 11 are then attached to piece 2 utilizing neoprene bolts,nuts and washers, pieces 5, 6, and 10 as depicted on FIG. 5, byinserting 10 thru the holes 13 in the pieces 7 and 11 and holes 13 inpiece 2 as depicted FIG. 2 and FIG. 4. The neoprene bolts are designedto comprise during the concrete curing process and allow the armorjoints to separate as the concrete floor cures. Pieces 5 and 6 are thenused to secure pieces 7 and 11 to piece 2.

Pieces 7 and 11 are fabricated in an assembled piece by attaching a stubat 30 degrees as depicted on FIG. 4. by welding. Piece 8 is a threadedcoupling which is also attached by welding. Piece 9 is a threaded boltwhich is threaded thru piece 8 and provides an adjustment mechanism forheight adjustment of pieces 7 and 11. By turning piece 9 either in theup or down direction height adjustment is achieved to provide an evenand level plane of top edges of piece 7 and 11.

The invention is assembled and set in place as one assembly. Theadjustment of the height of the top plane of pieces 7 and 11 areachieved by setting these components to required elevation via apreviously set benchmark elevation for the finished floor slab.

1-9. (canceled)
 10. The concrete armored joint form is comprised of aone step, set in place and leave in place concrete armored joint formthat provides thermal transfer prevention along with a seating systemwhich thereby captures the joint fill material. Furthermore, theconcrete form is comprised of an adjustability of the steel armor jointto compensate for undulations in the grade or the insulated floormaterials.
 11. The concrete armored joint form according to claim 10, iscomprised of two pieces, including a plastic composite base attached toa plastic upright form and steel armor joint components fitted withheaded studs, to provide for anchoring in the concrete slab. The armorjoint steel is attached to the plastic upright form which allows for aone step setting and a leave in place installation.
 12. According toclaim 11, the plastic upright component of the concrete armored jointform provides for a thermal break property, thereby eliminating anythermal transfer between concrete floor slabs.
 13. The plastic uprightcomponent according to claim 12 of the concrete armored joint form isgrooved on the top horizontal surface to provide a seating base for thejoint fill material.
 14. The concrete armored joint plastic uprightcomponent according to claim 13, is fitted with armored joint steel andis attached to the plastic upright component by means of comprisableneoprene bolts and nuts.
 15. According to claim 10, the armored jointsteel is fitted with attached jack bolts which therefore enables avertical adjustability feature.
